Reading the replies of OP it seems that he made up his mind and never call it a quits and just planning to hold some and diversify the rest and it's a good and wise move to do. Cryptos are just starting its era so it's too early to call it quits and I think no one in the right mind will quit when he knew that he can profit big.
Exactly! The one who has managed to earn this much amount of money is no doubt really a lucky person. I dont think so that he should quit all this thing as he knows the trick of making money and he can use the similar kind of technique in the future as well in order to make more money. Bitcoin can for sure later on make him the worlds richest person if he continued doing working hard in future as well.
